Great empires look ahead. Keep your traditions in mind, yes, but the past should be a guide, not a fetter. Break from the old faith. Break from centuries of squabbling on the continent. Break from old modes of production. Stride boldly into a future of new science and power guaranteed by our sails, backed by our army. Rule Britannia.

Rule Britannia is a new immersion pack for Europa Universalis IV. Immersion packs are designed to add greater depth and focus to the historical legacy of a particular region and Rule Britannia takes the history of the British Isles as its priority.
